A leisurely ride to enjoy refreshment and aircraft viewing at the Crew Room Cafe on Denham Aerodrome. Out on roads via Mill End and Chorleywood, past the Chalfont Open Air Museum. Return on roads via Denham Garden Village to join the Grand Union Canal Towpath at the, now closed, Bear on the Barge pub. Then ride the towpath to the Aquadrome. Only 717’ of climbing, nothing challenging.
